DRILL.

SPECIFIGATON forming part of Letters Patent N0. 695,786, dated March 18,1902.

Application filed July 25, 1901.

To all whom t may concern:

Be it known thatLWILLIAM G. BoLUs, a citizen of the UnitedStates,residing at Peoria, in the county of Peoria and State ofIllinois, have invented certain new and useful Improvements inGrain-Drills; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

This invention has reference to grain-drills, and especially to thatclass of drill known as shoe-drill, wherein the shoes are arranged toform furrows for the seed by displacing the earth by pressure.

The object of my invention is the provision of spring-pressure mechanismfor readily and easily pressing the drill-shoes in the earth and at thesame time leave them free to rise separately in passing overobstructions.

A further object is the provision of draft and spring-pressure devicesconnected direct with the tube of the shoes and arranged with a slidablemember for increasing or decreasing the tension of the spring-pressuredevice, and to mechanism for raising the shoes from the ground when theimplement is not in use or when transporting it from field to field.

The machine in its general organization and arrangement of parts may besimilar in construction to those now in use and need therefore bedescribed in detail only so far as is necessary to an understanding ofmy improvement.

In the drawings, Figure lis a side elevation, partly in section, of myimproved attachmentA to grain-drills, illustrating by the addition ofdotted lines the several positions in which the parts are capable ofbeing adjusted. Fig. 2 is a plan view of Fig. l. Fig. 3 is a perspectiveView illustrating the slidable member carried by the draft andspring-pressure bars. Figs. 4 and 5 illustrate in elevation andsectional plan certain details.

Like numerals indicate corresponding parts throughout the tigures, inwhich- 1 represents transverse frame parts supported upon ground-Wheels2 and carry frame parts supporting the seedbox 3.

4 refers to the axle connecting the ground- Wheels 2, the same beingsuitably journaled Serial No. 69,683. (No model.)

in boxings at opposite end of the frame and in a center frame-support 5,carried by the inner frame l.

6 represents rectangular rock shafts, at 55 their outer ends journaledin suitable supports and their inner ends carried by the tubular sleeves20, having a bearing in a tubular support 7 of the frame 5.

8 indicates the feed-tube, connected with a 6o suitable shoe at itslower end, and 8a represents laterally-extended lugs from opposite sidesof the annular iange at the upper end of the tube 8, and 8b indicatesdraft-rods secured to the forward ends of the runners or shoes and theirupper ends pivotally mounted on trunnions of the castings 12, attachedto the front face of one of the frame-bars l, as shown in Figs. l and 2.

9 indicates duplicate pressure-bars, detach- 7o ably connected at theirfront ends in a casting 1l by being slipped into the perforations ordepressions 11, and their rear ends, eX- tending rearwardly on each sideof the tube, lie beneath and adjacent to lugs S, and 15 is 75 a casting,the function of which will be further described, to which the rear endsof the bars 9 are attached by inserting them through perforations in thesame and retain' ing the same in such position relative to the 8ocasting by Cotter-pins dropped through perforations in the ends of thebars 9, as shown.

The casting 11 is provided with suitable perforations, by means of Whichthe same may be pivotally mounted on trunnions of the castings 12 afterthe draft-rods 8b have been adjusted in position.

10 indicates a draft and spring-pressure bar, the forward end of whichis detachably attached to the casting 11 by being inserted into 9o aperforation or slot 11b, and the rear end is attached to the upper endof the tube by connection with a lug or extension l0a from its frontface, as shown.

18 is a member slidably connected or se- 95 cured on the draft andspring-pressure bar l0, and the same is `provided with laterally'-tapered extensions 19 from opposite sides, arranged to be carriedbeneath and lie adjacent to the under face of the pressure-bars 9. rooThe arrangement of the bars 9 and 10 and their connection with thecasting l1 and tube are such that they lie approximately parallel toeach other, which permits of the connection of the slidable member onthe bar with the pressure-bars 9, as shown. Thus it will be seen thatthe adjustment of the slidable member 18 toward the casting-11 or thetube 8 decreases or increases the tension of the spring-pressure bars 9and l0.

13 indicates suitable castings attached to the rock-shaft Gand areprovided with the bifurcated extensions 14, and 17 represents shortlinks or straps pivotally connected with the free ends of the extensions14 and at their opposite ends have a pivotal connection with lips orlugs 16, extending up from the casting 15.

It is understood that the parts above described are arranged in series,and the mechanism for raising or depressing the tube and shoes comprisethe segment-rack 21, forming a part of one of the tubular sleeves 20,and the lever 22,having connection with the sleeve in any desiredmanner.

The operation of the device will be readily understood by an examinationof the drawings, from which it will be seen that to raise the shoes whentransporting the machine the lever 22 is raised to its highest point,(indicated by the dotted lines in Fig. 1,) which causes the arm 9,through the rock-shaft and connection of the same with the arms, to bearagainst the lugs 8fL of the tube 8 and raise the same. The bars 9 andthe draft and springpressure bar 10, through their connection with the'casting 11, will swing on the trunnions of the casting 12, as shown,and for pressing the drill-shoes into the earth the movement of thelever is just the reverse, throwing it into the position indicated. indotted lines in the same figure. This movement of the lever will forcethe bars 9 downwardly away from thelugs 8 of the tube 8, impart pressureto the draft and spring-pressure bar '10 through the lugs 19 of theslidable member carried thereby, which willimpart direct pressure to thetube through the connection of the bar 10 with the lip 10a for pressingthe shoe into the earth, the adjustment of the slidable member, assuggested, increasing or decreasing the pressure upon the shoe, asdesired.

I do not wish to limit myself to the construction of parts coperating asa whole to the successful operation of my device, as I am aware thatvarious changes may be made in the casting supporting said devices anddetails throughout resorted to without affecting the principle ofapplying my invention to obtain direct pressure upon the shoe and tube.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent of the United States, isf.-

1. In a grain-drill, the combination with conducting-tube, shoe anddraft-rods, the draft-rods pivoted to trunnions of the frame, a suitablecasting having a pivotal connection with said trunnions,spring-pressurebars connecting with the casting and having a bearing relation withdevices ofthe tube, a supplemental spring-pressure bar attached one endto the tube and the opposite end to the casting and a slidable member onthe supplemental bar having a bearing relation to the aforesaid bars,substantially for the purpose described.

2. In combination with the frame of a graindrill, and a tube having apivotal connection therewith through suitable draftrods, ofspring-pressure bars pivotally connected to the frame and their freeends lying adjacent to extended devices of the tube, mechanism forraising or lowering said bars, a slidablyarranged member engaging thelower faces of the bars having connection with means connected direct tothe tube, arranged when the spring-pressure bars are depressed to forcethe tube into the earth, substantially in the manner herein shown.

3. In a grain-drill, the mechanism for applying spring-pressure to theshoes thereof, comprising the pressure-bars 9 and lO, said barsconnected in a single casting pivotally connected with the frame, of theslidably-arranged member 18 on the bar 10, and extensions 19 lyingadjacent to the faces of the bars 9, in combination with connectingdevices of a rock-shaft and extensions of the shoes for raising the sameor imparting direct pressure upon the shoes for depressing the same,substantially as described.

4. The mechanism for depressing or raising drill-shoes of a grain-drill,comprising in combination with the tube, shoe and draft-rods, a swingingcasting pivoted to trunnions of the frame, duplicate spring-pressurebars detachably connected with said casting and their rear ends engaginglaterally-extended lips of the tube, and joined by a casting havingconnection with mechanism carried by a rock-shaft, a spring-pressure barlying between and approximately parallel with the aforesaid bars, itsfront end connected with the casting and its rear end secured in asocket of the tube, and a slidably-arranged member of the bar havingdevices engaging the lower surfaces of the duplicate bars, theadjustment of the member on the bar increasing or decreasing the tensionof the spring-pressure devices, substantially as described.

5. In combination with tube,shoe and draftrods, the casting 11, pivotedto the frame and provided with a series of perforations or slots, aseries of spring-pressure bars connected with the casting in theperforations, one of said bars having a positive connection with thetube, adjustably-carried tension devices between the bars, and arock-shaft arranged with castings having connection with devices of theouter bars of the series for raising the shoes or depressing the samethrough the bar having a positive connection therewith, substantially asdescribed.
